Description

Automobile roof covering piece

Technical Field

The utility model belongs to the technical field of automobile body structure manufacturing, and particularly relates to an automobile roof covering piece.

Background

As the automobile industry develops, automobile manufacturers have to use thinner steel plates as the outer covers of automobiles in order to save energy consumption, meet strict emission standards, and protect the environment, thereby causing the outer covers to become soft and to be dented by their own weight or a light impact. In the prior art, an inner plate and an outer plate are generally adopted to form a closed section so as to improve the integral rigidity, and the inner plate is mounted on a vehicle body. However, because the inner plate and the outer plate are usually connected in a spot welding mode, the welding point is easy to bulge or break after being impacted by vibration along with the prolonging of the service life.

the utility model provides a car roof covering, is including covering planking and the cover inner panel in automobile body top, cover inner panel length direction and extend to interior bending after, cover the inner panel and buckle the end surface and seted up the heavy groove that sinks, it is equipped with the equalizer plate to sink groove cell wall subsides, the equalizer plate surface is equipped with the connecting bolt that is connected with the cover planking, it has the recess of bending to cover the inner panel along its width direction extension, the recess outside of bending is equipped with the blank pressing that extends with the direction, the blank pressing surface is laminated in covering planking bottom, the lightening hole has been seted up to the recess tank bottom of bending, lightening hole peripheral ring is equipped with a plurality of enhancement recesses, it radially extends to along the lightening hole to strengthen the recess inner wall of bending.

Preferably, the covering outer plate and the covering inner plate are buckled with each other, and the outer edges of the covering outer plate and the covering inner plate which are attached to each other are fixedly connected in a welding mode.

Preferably, the side wall of the inner covering plate is provided with a positioning hole, and the positioning hole is arranged on the inner side of the bending groove.

Preferably, the positioning holes are arranged at intervals, and the number of the positioning holes is at least three.

Preferably, the width of the edge pressing is not less than 5 mm.

Compared with the prior art, the utility model has the beneficial effects that:

the length directions of the outer covering plate and the inner covering plate are arranged to be bent and buckled internally, so that the outer covering plate and the inner covering plate are attached to an automobile body structure, and the impact on the automobile body covering part is relieved by bending, and the covering part is prevented from deforming; the covering outer plate and the covering inner plate form an organic stress body which is mutually supported by utilizing the blank pressing, so that the body tension of the body covering part is dispersed to the maximum extent, and the stress performance of the covering part is enhanced; through set up the equalizer plate in the heavy groove of sinking, utilize the equalizer plate to cover planking and cover the interior plate and firmly connect, improve the connectivity between the two.

FIG. 2 is a schematic view of the structure of the cover inner panel according to the present invention;

fig. 3 is an enlarged schematic view of a portion a of the inner cover plate in the present invention.

In the figure: 1. covering the outer plate; 2. covering the inner plate; 3. sinking the tank; 4. a pressure equalizing plate; 5. a connecting bolt; 6. bending the groove; 7. pressing edges; 8. lightening holes; 9. reinforcing the grooves; 10. and (7) positioning the holes.

Detailed Description

The utility model will be further described with reference to the following drawings and detailed description:

as shown in fig. 1-3, an automobile roof covering element comprises an outer covering plate 1 and an inner covering plate 2 covering the top of an automobile body, wherein the outer covering plate 1 and the inner covering plate 2 are buckled with each other, the outer edges of the outer covering plate 1 and the inner covering plate 2 are fixedly connected by welding, the inner covering plate 2 is bent inwards after extending in the length direction, a sunken groove 3 is formed in the surface of the bent end of the inner covering plate 2, a pressure equalizing plate 4 is attached to the groove wall of the sunken groove 3, a connecting bolt 5 connected with the outer covering plate 1 is arranged on the surface of the pressure equalizing plate 4, a bending groove 6 extends in the width direction of the inner covering plate 2, a blank holder 7 extending in the same direction is arranged on the outer side of the bending groove 6, the width of the blank holder 7 is not less than 5mm, the surface of the blank holder 7 is attached to the bottom of the outer covering plate 1, a lightening hole 8 is formed in the bottom of the bending groove 6, a plurality of reinforcing grooves 9 are annularly arranged on the periphery of the lightening hole 8, the reinforcing groove 9 radially extends to the inner wall of the bending groove 6 along the lightening hole 8. Wherein, in order to arrange the solder joint for the convenience, improve the connectivity of blank holder and cover planking, set up the width of blank holder not less than 5 mm.

In the utility model, the covering outer plate 1 and the covering inner plate 2 are arranged in a length end bending shape, so that an arc-shaped cavity is formed between the automobile body covering part and the automobile body, the impact force of the covering part in the automobile body driving process is relieved, and in addition, the covering outer plate 1 and the covering inner plate 2 enable the covering part to be an organic stress body which is mutually supported through edge pressing, so the impact of the covering inner plate is dispersed to the maximum extent, and the stress performance of the covering part is enhanced.
